Discover classic island living in this charming 1870 late Victorian-era New England farmhouse, privately set on approximately 6.8+/- acres of open meadow and woodland just north of Big Tree Beach. Sweeping easterly views extend across East Penobscot Bay toward Cape Rosier, Castine, and beyond, while a cleared woodland path and recently built boardwalk lead to approximately 560' of protected pebble beach at Billy's Shore—a peaceful cove between Fire Island and Northeast Point that is ideal for beachcombing, relaxing, and boating access. The approximately 1,636-square-foot home offers two bedrooms, two full bathrooms, a flexible bonus room, first-floor laundry, and large sliding glass doors opening to a spacious, recently expanded deck overlooking the bay. Recent improvements include foundation and attic insulation, several new Andersen windows, new roof shingles, first-floor flooring, a new hot water heater, an improved boardwalk to the beach, and a more open bedroom layout. A 24-by-24-foot detached garage and workshop, along with a 12-by-12-foot shed, provide excellent storage and workspace—an inviting coastal retreat with character, privacy, and exceptional water access.
Magnificent views of East Penobscot Bay from this 1870's Greek Revival year-round three-bedroom home centrally located just north of the Narrows on almost seven acres of open meadow abounding with lupine. Inviting path and foot bridge through the woods to 560 feet of smooth gently sloping beach. Kitchen, dining, living rooms, knotty pine sunporch, bath and half. Detached garage and shed. Many possibilities from this LOCATION! $379,000.
